ABSTRACT

BACKGROUND AND AIM: Despite advances in modern medicine, the development and growth of calculi continues to be a source of concern for mankind, as there is no effective treatment for kidney stones. In the present study we investigated antiurolithiatic activity of Bryophyllum pinnatum Lam against sodium oxalate (NaOx) induced urolithiasis in rats. EXPERIMENTAL PROCEDURE: In rats with renal calculi caused by sodium oxalate (NaOx, 70 mg/kg, i.p.); the antiurolithiatic action of Bryophyllum pinnatum hydroalcoholic extract (BPHE) was studied. BPHE was given every day orally at doses of 50, 200 mg/kg for 14 days to rats to examine activity against sodium oxalate (NaOx) mediated urolithiasis, with Cystone (500 mg/kg, p.o.) as a reference standard. The effect of the extract on urine oxalate, creatinine and phosphate retention and excretion in the kidney, as well as serum and biochemical analysis of kidney homogenate and histopathological examinations were studied. RESULTS AND CONCLUSION: Oral administration of BPHE at doses of 50,100, and 200 mg/kg to rats with sodium oxalate-mediated renal calculi showed dose-dependent substantial (P<0.05) antiurolithiatic potential, with notable reversal of NaOx-induced ion excretion and urinary CaOx concentration. These findings justify the traditional use of Bryophyllum pinnatum hydroalcoholic extract (BPHE) in the treatment of renal calculi.

ABSTRACT

Present study was carried to find out the antihyperglycemic and antihyperlipidemic activity of ethanol and aqueous extract of Thespesia populnea fruit pulp on alloxan-induced diabetic rats. Diabetes was induced in rats by administration of alloxan (150 mg/kg, i.p.). After the successful induction of experimental diabetes, the rats were divided into five groups each comprising a minimum of six rats. Phytochemical analysis and acute toxicity study of extracts was also done. The effects of extracts and metformin on fasting blood glucose and plasma lipid were examined for 28 days. Statistical analysis was carried out by using analysis of variance followed by Dunnet's multiple comparison test and paired t-test were done as the test of significance using GraphPad Prism. P≤0.05 was considered as the minimal level of statistical significance. Therapeutic dose of extract was found to be 200 mg/kg on the basis of acute toxicity study. Aqueous and alcoholic extract showed a significant reduction in blood glucose levels as well as a lipid profile of diabetic rats at the end of 28(th) day of treatment. However, in groups treated with plant extract the reduction in the blood glucose and improvement in lipid profile was slightly less than that achieved with the standard group (metformin). From this study, it can be concluded that ethanol and aqueous extract of Thespesia populnea exhibited significant antihyperglycemic and antihyperlipidemic effects on alloxan-induced diabetic rats.
